A Botanical Report for Six Areas Designated for Possible Alteration or Disturbance in Selecting a Receiver Site

for Sediment from Behind the San Clemente Dam

July 21, 2005

(Field work: May 25, 30 & June 10, July 21, 2005)

As part of the California American Water Company’s Seismic Safety Project for San Clemente Dam, botanical data has been gathered by the writer and others while methods and routes are being studied for determining a receiver site and a route of transport for sediment from behind San Clemente Dam. This report is designed to provide botanical data for six areas some of which may have been previously studied. The areas may be variously impacted depending on the proposed use, i.e. transport or receipt of the sediment. Personnel of ENTRIX, Inc. will determine methods to be used, areas to be transversed, and the location(s) of the receiver site(s).

I. Introduction

I was contacted by Mr. Jeremy Pratt of ENTRIX, Inc., Seattle, Washington, to perform certain botanical surveys based on marked aerial photographs and Geodetic Survey Maps. Ms. Gretchen Lebednik was the principal person to oversee the work to be done. She provided a target list of species to be watched for and indicated the style of report she wished to receive. While the work was scheduled for earlier in May, certain delays prevented the marked overlays from arriving. Rainfall for the entire winter made the unimproved access roads inadvisable at best and impassible for part of the period. Mr. Don Lingenfelter, Dam Keeper for Cal Am, provide access keys and advice on road conditions.

II. Regional Setting

The area studied is within the Carmel Valley quadrangle and essentially lies south and east of San Clemente Dam. The terrain generally slopes westerly and northwesterly from Tularcitos Ridge and Cachagua Rd. to the Carmel River. Carmel Valley Village is to the northwest. The elevations encountered are from approximately 1400 feet at the Cachagua Rd. entry to approximately 540 feet at the San Clemente Dam.

Following Robert Holland’s Natural Communities of California, the area vegetation generally is composed of five types. These are: Interior Grasslands, Coast Live Oak Woodland, Coast Live Oak Savanna, Adenostoma Chaparral and River Riparian Forest similar to Holland’s Central Coast Cottonwood-Sycamore Riparian Forest.

In attempting to follow Sawyer and Keeler-Wolf A Manual of California Vegettion California Native Plant Soc. 1995 and California Natural Diversity Database List of California Terrestrial Natural Communities Recognized by the California Natural Diversity Database May 2002 Edition, some comprimises must be made. The grasslands are most like the Nodding Needlegrass Series. But the present grasslands are mostly dominated by introduced annuals with occasional lenses of more concentrated perennials. The Coast Live Oak forested areas follow the Coast Live Oak Series. The Adenostoma chaparral is within the Chamise Series. No logical vegetation type appears to cover the mixture of plants occuring in the alluvial fans above the San Clemente Dam. However sycamore trees are present as a species, but no forest of that taxon is present. The mixed chaparral of the diversion canal site falls within the Chamise Series.

III. Local Vegetation

The method used in determining the local vegetation was to walk the areas designated while recording the various plant species present. This included the possible transport route along an existing access road from Cachagua Rd. to and including the 4R sediment disposal site. Also transversed was the route of a proposed road leading from the disposal site downward to the Carmel River. The areas above San Clemente Dam were also walked. These included a proposed sediment transport route between San Clemente Creek and the Carmel River, the area of a diversion dyke on the Carmel River, and the proposed diversion canal between San Clemente Creek and the Carmel River. As one might expect, the existing road route from Cachagua Rd. produced the greatest variety of vegetation because it transversed many of the habitats. The ungrazed grassland areas

were greatly overgrown by a dense thatch of introduced grasses influenced by this year’s continual series of rainstorms that provided moisture the entire winter. This made growing conditions difficult for the smaller forbs, causing them to be shaded out and nearly impossible to find. The Adenostoma Chaparral was also greatly overgrown so that smaller forbs were shaded out. A seed bank of numerous species will be present within the soils of that habitat element. These species will appear following any future wildland fire. The proposed road extension produced a repeat of plants already found. Additions to the species list began to appear when the area of the dam reservoir was reached. The river area added considerably to the species list as did the east-facing slope of the area proposed for a diversion canal.

Coast Live Oak Forest (Coast Live Oak Series) is the principal upland habitat present. Site 4R is a steep canyon with a closed canopy of Coast Live Oak Forest plus a few additional tree species and tree sized shrubs such as toyon. The disposal site understory is mostly a dense tangle of poison oak, snowberry and shade tolerant ferns and shrubs reaching for light. The canyon is dry except for a bit of moisture flowing along its lower level near the dam reservoir. One might have expected surface water here and there in the canyon because of the abundant winter rains, but drainage flow had mostly followed previously cut channels without retaining surface water or feeding springs.

The plant lists show a preponderance of native species some of which were recorded as single plants. The entire area in actuality has a general intrusion of weedy grasses and introduced forbs numbering fewer in numbers of species but very large in numbers of individuals.

IV. & V. Rare and Endangered Plants or Communities

No rare or endangered plant species were found.

VI. Special Plants

Lewis’s Clarkia Clarkia lewisii was found along the entry road from the Cachagua Grade. It is a California Native Plant Society List 4 species. A plant appearing on List 4 is not an indication of rarity but rather a request for information concerning its abundance and distribution. Lewis’s Clarkia is common on road banks in Monterey County especially in the Santa Lucia Mountains. Eventually the Native Plant Society will determine the scarcity-abundance of this species, but is currently only requesting information on its distribution. The California Department of Fish and Game's publication called Special Plants lists the species in its publication by that name. The publication is dated 2002.

VII. Impact Assessment

To be determined in the EIR process.

VIII Mitigations

To be determined in the EIR process.
